To all whom it may concern Be it known that l, lim'ssi-zs G. LEE,citizen of the lnited Staten, residing at Brooklyn, New York, haveinventedcertain new and h lt ill Improvements in inking-Ribbon Mechanismfor .-.(l(lres 1ing'-Machines, of which the following is aspecification.

My present invention is a division of that disclosed in application forLetters Patent of the United States; filed by me .etugusat lo, 100%, No.313044, and consists in the features and combination.of parts relating;to the ribbon movement as hereinafter described and particularly pointedout in the claims.

In, the accompanying drawings:Figure l is a front view of a machineembodying my invention; l i is a plan view; Figs. 3, 'i l3. 7 and 8 areviews of (lGitlllH; Figs. 9, 10, 11 and 12 are views ,ot' furtherdetails.

I. hate shown my invention a; applied to a machine for printingaddresses or the like from printing plates which are taken one by onefrom a hopper A. at the right of Fig. .l, and moved by a conveyor chainB to a point beneath an impression pad 8, which is operated verticallythrough an arm (3 from suitable operating connections. The paper ormaterial upon which the impressions are made is fed into place ben aththe impression pad 8 in any suitable manner not accensary to describeherein hut disclosed in said application above referred 'o.

For making the imprenions, I employ 21 ribbon L extending over the pathtraversed by the priming plate and beneath the iniprcssion pad 8. Thisribbon is attached at one end to a. ribbon reel to, Fire. 1, 2 and T,loosely mounted on a. sleeve M, which, in turn, is looaely mounted on'apin aupportcd in the frame. This loose sleeve ll driven from the shaft Bthrough a suitable h ll; and belt wheels I), 7), on the shaft B and thesleeve M, respectively. Driving, connection is made between the reel andthe sleeve lll: by means of a friction spring l5 carried by the reel.and hearing upon tl.e loose sleeve. The ribbon extends i'rom this reelaround a gni-zle pulley Y. and thence to a ribbon spool X fixed to ashatt- U, vith which is associated rib on reversing mechanism. Thisribbon reversing mechanism also controls the movement and the teed ofthe ribbon, which is about one-eighth of an inch for each impression.This mechanism com-' prises an arm N mounted to swing about the axis ofthe ribbon spool shaft U, and connected by a lint: 0 with a portion ofthe yoke (5, so that movement is imparted to the disk arm N at eachaction of the yoke, and, consequently, once for each impression. Thisdish aria carries two pawls P and Q, pivoted thereto at n. and it hasalso pivoted at this point a pawl controlling arm The paWls l and Q areada 'itctl to engage a ratchet wheel T, whi l1 fastened to the shaft U,and the direct. of rotation of the ratchet wheel T, with its ahat't ll,and consequently, the ribbon spool X. will do ventl upon which of thetwo pawls P and .over the roller 1", will, under this extra tension,impart movement to the said roller and its car vino lever Y against thetension 01. the spring Z. This lever will therefore swing laterally, andits arin Y will be thrown down to deprens a reversing stop C, removingthe same reve rag lever B, which now alto, a to roving about the axis ofthe .hat't ll 1 arrestral by a stop S, said swinging movement being dueto a spring l) hereinafter described. in this a tion of the reversinglever 5, its arm 3 carrying a pin #7 will *aune the shiftingof the pawlcontrolling arm ll. because of the engagement oi" the pin with thetor-lied end of the said controlling lever, and this controlling leverwill therefore throw the engaged pawl out ol engagement with toothedwheel '7? and throw the diaengagctl pawl into action, no that themovement of the shaft ll will now he reve sod from that which itformerly had, to unwind the spool and allow the ribbon to unwind step bystep tlwretrorn. about one-eighth of an inch at each action. 'lhemovement of the lever S is due to a torsional spring 1) connected to isin engagement witlrthe toothed wheel T.

therewith at one end surrounding the shaft,

and connected with a friction wheel E on the said shaft U. This wheel Eis driven from the shaft U by a friction spring 6 within it, and afriction leather 0. As shown in Fi 's. 10 and 12. the wheel la has anOverhanging flange which receives the friction This wheel has also astop pin 6 which,

when one revolution has been given to the wheel E and to the torsionspring, will strike against a stop pin a on the hub of the arm S, sothat the torsion spring will be wound up sulficiently in this onerevolution to have the required power for throwing the arm S when thestop pin C" is moved therefrom, and the torsional action willtakc placewhether the shaft U is moved in one direction or the other. in order toplace the main shaft U under a eel-tantamount of resistance, I providefriction washers V, V on each sideof the bearing 16 in which the shaft Uis journaled, and I employ a tension spring VT to place-a pressure onthese washers so that they will grip the bearing and hold the shaftfirmly against movement, e20 ceptwhen the friction is overcome by theaction of the driving pawl P or Q; carried by the lever ll.

Reverting to the action of the ribbon reel 15 in cmmection with theribbon movement and reversing mechanism just described, it should beobserved that tl 3 shaft l3 rotates one-half of a revolution for eachimpression, and therefore drives the. sleeve M upon which the ribbonreel is loosely mounted once for every impression. The friction spring15- causes the ribbon "eel to rotate suliiciently to take up any s [ckwhen the ribbon is moving from right to left, at which time the ribbonspool X is be ing rotated step by step to unwind the ribbox so that itmay pass therefrom and be.

wound on the reel 15, the action of each movement of the ribbon beingabout oneeighth of an inch, as above stated. When the ribbon is movedfrom left to right, the ribbon reel. 15 is rotated by the pull of theribbon, dueto the feed mechanism, in an opposite, direction to themovement of the sleeve M, the friction connection between the sleeve andthe ribbon reel serving merely to keep the proper tension on the ribbon,

and the operation is repeated. From the above it will be understood thatthe reversing actions take place immediately after the predetermined orsubstantially entire amount of ribbon has been wound on the spool, thenunwinding begins, and when the ribbon has been fully unwound, the spoolcontinues to rotate in the same direction to give an opposite rewind tothe ribbon, and this movement is continued until the spool is againfilled, when another reversing action takes place.

I claim as my invention 1. In combination, an impression member, aninking ribbon movement, including a ribbon spool at one end of theribbon, with means for operating the same, a ribbon reel at the otherend of said ribbon, connections moving in one direction only tending to0perate the ribbon reel in one direction, including a rotary onedirection friction member which, when the ribbon is to be wound on thereel, will drive the reel and which,

when the ribbon spool winds the ribbon, will tend to rotate the reel andthus place a, ten sion on the ribbon, substantially as described.
